IMPROVEMENT IN UNIVERSAL SAFETY-COUPLINGS.

Specification forming part of Letters Patent No. 120,145, dated October 17, 1871.

To all whom it may concern.-

Be it known that I, GUSTAVUS H. Zsonnon, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and valuable Improvementin Universal Safety-Couplings and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a longitudinal section of my improved safetycoupling taken across pin E. Fig. 2 is a longitudinal section of the same taken through the center of pin F.

This invention has relation to universal balland-socket coupling; and the novelty consists in the construction and arrangement of a segmental die applied to a ball-and-socket joint to relieve strain and increase the utility and durability of the coupling.

In the drawing, A represents the socket-section, 13 the socket, O the ball-section, and I) the ball. E designates the pin on which the ball is swiveled. It is traversed by the pin F attached to the socket. G represents a segmental slot cut in the ball on a plane at right angles to the axis of the pin E. Within said slot a segmental die, H, slides. The latter is pivoted to the pinF and turns around it with the ball, thus relieving the strain on the pin and preventing its too rapid wear from friction. The beveled projection I limits the pitch of the ball section.

I do not claim the ball-and-soclret coupling or the combination therewith of the oscillating cen ters F E; but

What I claim as my invention, secure by Letters Patent, is

The ball-and-socket joint having the segmental recess Gr, segmental die H, and pins F E, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GUSTAVUS H. ZSOHEOH.
